Now girls, help me out, if you know what I’m talkin’ about,” sang Christina Aguilera on the aptly titled “Underappreciated,” a terrific but lesser-known cut from 2002’s underrated Stripped CD. And sadly, that’s a sentiment familiar to the 64 participants in’s first annual Under-appreciated Entertainer of the Year single-elimination bracket tournament.

As Day 6 of our first-round matchups continue, you’re going to have some brutal choices to make: Project Runway‘s Mondo Guerra and Top Chef‘s Tiffany Derry already got robbed on their respective reality series this year, yet one won’t even survive the initial duel of this bracket game. Parenthood‘s Peter Krause has done incredible work on a show that’s struggling in the ratings, while Sara Ramirez somehow fails to get the same awards-season love as many of her colleagues on ABC’s hit Grey’s Anatomy. Alas, you can only vote for one of ’em.

We’re also showing mad love to some musicians and movie actors who deserve bigger commercial and/or critical success than they currently receive. In the former category, we’ve got Ray LaMontagne facing off against The Gaslight Anthem, and in the latter, it’s Tahar Rahim (A Prophet) taking on Joe Anderson (The Crazies).
